View Agent, what is installed?

20160710-01

While (re)installing the VMware Horizon View Agent you can choose from many features. (De)Selecting a feature can have a big impact on the user experience (Once a customer was very upset when he found out that Client Drive Redirection was activated…).
After finishing the installation of the View Agent, there is no easy way to review the features installed (as far as I know). Luckily, the log files created during the installation provide a lot of information.

Location of the log files: C:\ProgramData\VMware\logs.
Search for the latest vmmsi.log, these come in the format: vmmsi.log_yyyymmdd_hhmmss.
Note, there are also log files starting with vminst.

Open the log file with your favorite editor.

Install VMware Tools in CentOS 7

08/07/2016

20160708-01The VMware Tools are an essential part during the installation of a Virtual Machine. For many Operating Systems you can go the easy way and install the VMware Tools right from the vSphere Web Client. You will install the VMware Tools that comes bundled with vSphere ESXi.

BTW, Since September 2015, there is also a downloadable version of VMware Tools (versions 10.0, 10.0.5, 10.0.8 and 10.0.9). The Downloadable versions (should be seen as a Solution) support all version of ESXi from 5.0 and later, see VMware Product Interoperability Matrixes. See the release notes of the latest version.

So far so good, for Windows Operating Systems, the installation of the VMware Tools is a no brainer. For Linux operating systems, installation is more complicated, for most reasons because Linux Operation Systems do have multiple options to install software.

In my case, I usually work with CentOS (based on the sources of Red Hat Enterprise Linux RHEL). CentOS uses RPM as a packet manager. Packet Managers do have many advantages while maintaining a Linux server. Unfortunately, the bundled version of the VMware Tools doesn’t come in .rpm format, but as an archive file in tar.gz format. Although installation of a .tar.gz is straightforward, it is not the way to go.

An alternative is using VMware’s OSP repository, see this nice post in case you want to know more. You can browse the OSP repository here. For CentOS, browse the corresponding RHEL version. You will also notice that there is no entry for RHEL7. Trying the RHEL6 version failed in my case.

VMware Certified Advanced Professional 6 – Data Center Virtualization Deployment Beta Exam

14/05/2016

VMW-LGO-CERT-ADV-PRO-6-DATA-CTR-VIRT-DEPLOY-K

Update 12-6-2016: The VMware Certified Advanced Professional 6 – Data Center Virtualization Deployment Beta Exam (3V0-623) is available for a short time, starting 15 June 2016. As the official post states, the exam will not be available in all regions. More information, blueprints and registration can be found here.

I recently stumbled upon the VMware Certified Advanced Professional 6 Data Center Virtualization Deployment Beta exam, probably the successor of the famous VCAP5-Data Center Administration exam. Passing this exam is the final step on your road to the VCAP6-DCV Deploy Certification. For more information about the requirements, have a look at this page.

In the past, I have written two Study guides to help you pass the VCAP5-DCA exam, being the VDCA510 (vSphere 5.1) and VDCA550 (vSphere 5.5) exam. So with this new VCAP6 exam, let’s have a look at the changes.

So let us compare the objectives of this new VCAP6 with latest VDCA550 (vSphere 5.5) exam.

First, the name of the exam and the certification has been changed; in VCAP6 it’s “Datacenter Virtualization Deployment” instead of “Data Center Administration

Second, I have always wondered why the objectives started with Storage- and Network Infrastructure, instead of the Infrastructure components (vCenter Server, ESXi etc.). This Exam Blueprint starts with “Create and Deploy vSphere 6.x Infrastructure Components”, which makes more sense to me.

It will be no surprise that the objectives have not been completely changed and contain many objectives found in previous editions. A brief overview of the objectives, where applicable a reference to the VDCA550 (vSphere 5.5) exam has been made ( ==> <VDCA550 Objective>).

Deploying replica fails with .vmdk access errors

24/04/2016

A quick post about an annoyance I encountered while recomposing a View Horizon Linked-Clone desktop pool to multiple local datastores. In this situation multiple replicas will be created from the Parent VM.

These replicas are created simultaneously; however during this process the task pane in the vCenter Server shows many .vmdk access errors on the parent VM and as a result replicas are created one after the other.

VMware KB “Deploying multiple virtual machines in VMware vCenter Server 5.x and 6.0.x from the same template fails with the error: vmdk access error (2114026)” explains that this issue occurs because of locked –ctk.vmdk files. These files are part of the Change Block Tracking (CBT) mechanism. The KB provides instructions how to modify the settings of the Parent VM by disabling CBT.

However after editing the .vmx file and deleting the –ctk.vmdk files from the datastore, the files reappeared immediately. To resolve this behavior, SSH to an ESXi host and browse to the datastore where the Parent VM is located.
Then, edit ALL .vmdk files and remove or comment out the line starting with; changeTrackPath=.


2016-04-24-01Figure 1

Now, the –ctk.vmdk files will be gone for good.
To prevent third-party applications from enabling CBT, you can add the following line to the .vmx file of the Parent VM: ctkDisallowed=”true”.
As always, I thank you for reading and welcome your comments.
